Mechanical Measures of Spasticity in Stroke

Abstract

Mechanical measurements of stretch reflexes show promise for the quantification of spasticity after stroke. Mechanical measurements can increase the objectivity, repeatability, and precision of spasticity quantification and provide additional insight into the neuropathology that is not available with current clinical measurements. Several techniques are reviewed and the advantages and disadvantages of quantification of spasticity using mechanical measurements are considered. Although mechanical measures of spasticity offer many advantages, much research needs to be done to establish a standard measurement of spasticity that can be easily implemented in the clinic.
